The New Democrats: An intellectual history of the Green Wave

What we are witnessing right now in the streets of Tehran is, first and foremost, a political battle for the future of the Iranian state. But closely linked to this political fight is also an old theological dispute about the nature of Shiism–a dispute that has been roiling Iran for more than a century.

Shiism, like most religions, is no stranger to heated schisms. Shia and Sunnis split over the question of whether Muhammad had designated his son-in-law, Ali, as his successor (Shia believed he had). Some Shia, called Alawites, believe the only divinely designated successor was Ali, while another group, Zaydis, believe there were four imams. A large, intellectually vibrant third group is known as the Ismailis because it believes the line of imams ended with the seventh, Ismail. And the largest Shia sect is called the Ithna Ashari–or the Twelvers. Dominant in Iran, they believe in twelve imams and posit that the last imam went into hiding some 1,100 years ago. His return, bloody and vengeful, will mark the redemptive dawn of the age of justice.
